SPRING- WHEEL.

l Application led October 27, 1922. Serial No. 597,309..

To all 'whom t may cof/wem.'

Be it known that l, FAUSTINO PALoMo, a citizen of the United States, and a resident of Bedford, in the county `of Cuyahoga and State of Ohio, have invented a new and 1mproved Spring Wheel, of which the following is a full, clear, and exact descript1on.

This invention relates to improvements in spring Wheels, an object of the invention being to provide an improved arrangement of springs and mounting therefor whereby all of' the springs function to cushion the ve the maximum resiliency and strength with the minimum of weight.

A further object is to provide a spring wheel havinga series of bow springs intera posed'between the inner and outer members ofthe wheel, said springs having fixed rela-l tion to one member and at their ends having movable or 'rolling engagement with the.

- other member whereby the springs can take varying positions in accordance with the strains and stresses put thereon.

A further object is to provide a spring wheel .in which resiliency is provided by a pluralityof leafed bow springs, the intermediate portions of which are xed to one member of the wheel and the end. portions ofthe springs have rolling engagement with A arcuate tracks on the other member.

A further object is to provide a spring wheel of the character stated in which a sectional core preferably of wood is provided in the shoe or tire ofthe/wheel so as to reduce the weight to a minimum and provide a puncture proof tire.

A further object is .to provide a spring wheel 0f the characterstated which can be manufactured and sold at a reasonably low price, which will be neat and attractive in appearance, which will be relatively light inweight and which will most efiiciently perform the functions for 'which lit .is intended.

With these and other objects in view, the invention consists in certainnovel features of construction and combinations, and arrangement of parts, as will be more fully hereinafter described and pointed out in lthe claims. w ln the accompanying drawings-- f Figure 1 is a view partly in-elevation butmainly in. longitudinal section illustrating my improved spring-wheel,

Figure 2 is a View in transverse section on the line 2-2, of Figure 1.

Figure 3 is an enlarged view in transverse section showing the mounting of one end of one of the springs.

l and 2 representl the inner-and outerV members of my improved spring wheel. The

inner membero 1 is of general circular or cylindricalv form,"and is secured to the axle 3 in any desired manner, and in fact, it is the purpose of my invention to so construct this inner-member 1 as to make 'it conform to standard axle construction and allowit to 1be positioned on any. ordinary automobile ax e.

The outer member 2 constitutes a casing circular or cylindrical inform and having an integral web 4 at its outer portion to give the wheel the necessary diameter.

Between the inner .and outer memb'eis 1 and 2 a series of springs 5 are interposed. These springs 5 I shall hereinafter refer to as bow springs, although they are preferably composed of a plurality of leaves and a preferable form is to provide veach spring with leaves of varying lengths, but it is to be understood of course, that my invention is not limited to the exact form of the spring except that it is of general' ow shape with its intermediate portion fixed by a Ubolt 0r other securing device 6 to the outer member 2, andy having clamping bands 7 thereon to hold the lea-Ves in proper assemblage.

Y The inner member lis formed at its edges with grooves constituting tracks 8, and these grooves or tracks 8 are extended by arcuate enlargements 1() on the member 1 so that the tracks, at their terminals, are curved in the arc of a circle with said arcuate terminals opposed to each other. A

The 4springs 5 at their ends, are provided with rollers 11 which run on the arcuate 'portions of lthe tracks, and these rollers 11 7 are connected by suitable journals 12 with anti-friction bearings 13 interposed between -ntial being that the rollers are so positioned as to run freely on the tracks and to compensate for varying positions of the ends of the springs to properly function in sustaining the load, and in absorbing the shocks v imparted to the wheel.

rllhe web 4, constituting the outer portion of the wheel is made with a. clincher rim section 14C and a removable clincher rim section 15 to secure a shoe 16 thereon and permit its removal as occasion may require.

Within the shoe 16 l locate a plurality of core sections 17, these sections 17 are preferably of wood for lightness and cheapness, and they have tongue and groove sections as shown at 25.

Furthermore` l( would call attention to the fact that the lines of juncture between the sections 17 are parallel with the diameter of the wheel, so that the sections can be readily drawn out of the shoe one at a time, or replaced in the shoe in assembling.

To facilitate the manipulation of the sections 17 l provide angular notches 18 in the sides thereof, and these notches are adapted to receive a suitable tool to facilitate the movement of the section. ,4

The casing portion or member 2, of the Wheel is adapted to contain oil or other lubricant 19 in its lower portion which splashes around inside of the wheel and maintains all of the parts properly lubricated. To prevent the escape of this oil, and also to prevent the entrance of dirt and grit into the` wheel, l provide a closure disk 2O against the inner facel of the wheel, which is secured to the brake drum or other portion 21 of the axle housing 22, and on the outside of the Awheel l provide a removable hub plate 23 which is tixedly and removably secured to the casing by means of screws 24 or in any other approved manner.

ln operation the load and the jars iinparted to the wheel cause the members l and 2 to move relative 'to each other. rlhe springs 5 sustain this load and absorb the jars, all the springs functionin at all times, but due to the varying positions of the springs as the wheel turns, the several springs will receive dierent torsional strains so that their ends will bend and this i endstof the springs are therefore more or less Messes l claim: 1. A spring wheel, comprising an inner member, an outer member, bow springs in-VA terposedbetiveen the members, and at their intermediate portion secured to one member, and at their ends having movable engage ment with the other member, and arcuate tracks on the last mentioned member guiding the movement of the ends of the springs.

2. A spring wheel, comprising an inner member having a plurality of opposed pairs of arcuate tracks, an outer member, bow springs fixed at their intermediate portions to the outer member, and at their inner ends movable on the arcuate tracks of the inner member.

3. A spring Wheel, comprising an inner member having a plurality of opposed pairs of arculate tracks, an outer member, bow springs fixed at their intermediate portions to the outer member, and rollers on the ends of the springs mounted to roll on `the arcuate tracks of the-inner member.

d. A spring-Wheel, comprising an inner member having a plurality of opposed pairs of arcuate tracks, an outer member, boiv springs fixed at their intermediate portion to the outer member, rollers at opposite sides of the ends of the springs having roller bearing mounting on the springs and engag-y ing the arcuate tracks.

5. A springfwheel, comprising inner and outer members, outwardly and laterally projecting portions on said innerme-iiiber, bow springs secured at their intermediate portions tothe outer member, said springs having inwardly rejecting free ends positioned under the said) outwardly and laterally projecting portions of the inner member.
